I have a bad record with 'lost ski areas'.
Here is the short list starting North and working South.
Cleary Summit ski area Fairbanks, AK
Ran the ski school there one winter. This is not the Chugach.
Independence Mine, north of Palmer, AK Taught a few clinics here famous for early season, everyone from european racers to local school kids showed up here. great hike to terrain.
Army Arctic ski bowl. Just outside Anchorage, AK. As a kid used to ride in deuce and a halfs to ski there in the 60's after school after school. It was a pretty good hill for $1.00/day
Pikes Peak Ski Area. I thaught there in high school for a couple of years, and learned a lot there including skiing. Buddy Warner won a race there.
Ski Broadmoor, Colorado Springs. Would night ski there in high school. It was a tilted ice rink with a chairlift.
There were others but not that I skied much at. You probablly should not let me ski at your ski area.
